dart2js generated code fails on safari

I wrote a simple app in dart with canvas and tested it in safari.

This appeared:
TypeError: 'undefined' is not a function (evaluating 'this.box_0.closure_1.$call$0()')

the app runs fine on safari with frog.

Can you provide a simple test case that fails? We know of a few issues with the browser compatibility of the dart2js output that we're fixing, but it would be nice to know if this issue is already covered by that work.

Added Area-Dart2JS, NeedsInfo labels.

Could be the same problem as described in issue #3025. The problem is the requestAnimationFrame method which works in frog but not in Dart2Js.

The JavaScript code is:

Isolate.$defineClass("Closure", "Closure6", ["box_0"], {
 $call$0: function() {
  return this.box_0.closure_1.$call$0();
 }
});

The Dart code would be helpful.

Just tested it with Dart Editor Build 8052, problem is still the same.

Dart code from issue #3025:

void main() {
    window.requestAnimationFrame(onAnimationFrame);
}

bool onAnimationFrame(var currentTime) {
  window.requestAnimationFrame(onAnimationFrame);
  print("$currentTime");
  return true;
}

I finally found the "Error Console" in Safari :)
Yes, it is the same error in Safari as it is in IE9.

Removed Priority-Medium label.
Added Priority-High, Triaged labels.
